The software package Dissolved Gas Modeling and Environmental Tracer Analysis (DGEMTA; Jurgens and others, 2020) was used to develop the solubility calculations. DGMETA produces estimates of dissolved gas concentrations during recharge as well as estimates of recharge temperature, excess air, and excess nitrogen gas concentrations by optimizing the solutions of solubility equations for multiple gases dissolved in samples of groundwater. These data were collected during...

The basin is underlain by interbedded shale and sandstone that have been variably hydrothermally altered and silicified by local magmatic intrusions. Samples were collected from 2017 to 2019 from bedrock monitoring wells completed at multiple depths, shallow hand-installed piezometers and mini boreholes, springs, mine adits, and streams. The tracer data include stable isotopes of water (oxygen-18 and deuterium), tritium, dissolved noble gases (He, Ne, Ar, Kr, Xe, and helium-3/helium-4...

Groundwater ages were estimated by calibration of environmental tracers (tritium, tritiogenic helium-3, chlorofluorocarbons, sulfur hexafluoride, carbon-14 and radiogenic helium-4) to lumped parameter models (LPMs) for 1,353 samples from 1,182 sample locations.

The objectives of our study were to quantify daily and weekly scale effects of an experimental flow regime on GPP in the Colorado River. The experimental flow was conducted at Glen Canyon Dam from May-August in 2018, 2019, and 2020 and contrasted steady-low flows on weekend days with business-as-usual hydropeaking flows during weekdays. This data release only contains data through 2019. These data represent daily-scale estimates of GPP, discharge, turbidity, water depth, and canyon shading for eleven reaches on the Colorado...

The U.S. Geological survey has published water and gas chemistry data from geothermal areas in the western United States, which is primarily available as scanned PDF files. This makes the data difficult to access or include in large-scale data analysis. This data release provides digitized and reformatted data from 20 previously published U.S. Geological Survey Open-File reports and journal articles, representing 1867 water chemistry samples and 313 gas chemistry samples.

In June 2011, nine groundwater samples were collected from selected wells and springs in the study area. The samples were analyzed for a suite of environmental tracers and dissolved gases that were used to model recharge temperatures and groundwater ages. All geochemical and environmental tracer results used in the models are available in the USGS National Water Information System (NWIS) using USGS station numbers.

American glass eels (Anguilla rostrata) were housed in buckets for 3 weeks at 14, 18, 22, or 26°C (n=5 buckets/treatment) to determine optimal juvenile rearing temperature in the laboratory. Initial weight (g) was recorded for each bucket. During the 3 week experimental period, data was collected on water temperature (°C), mortality, and the presence of gas bubbles. Water samples were taken to measure ammonia (mg/L) following the completion of the experiment. Final eel length (mm) and wet weight (g) were recorded for all eels in the study.
